DETAILED DESCRIPTION

[0021] Furthermore, the terms “first,” “second,” “third,” etc., are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0022] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which the various embodiments of the present application belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meaning as in the context of the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in the various embodiments of the present application.

[0023] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0024] Coiled material is a common material used in a wide range of applications, including packaging, construction, and transportation. It is characterized by its long length and is typically wound into a cylindrical shape for easy storage and transportation. The diameter of the coil directly affects its efficiency and storage space requirements.

[0025] The coil diameter usually refers to the outer diameter of the cylinder formed by the coil during the winding process, that is, the diameter.

[0026] Lithium battery production often involves the use of coils (e.g., electrode sheets). These coils are wound around a shaft for transport and processing. When the equipment begins operating, the coils need to be slowly unwound for further processing. As the unwinding process progresses, the coil's diameter gradually decreases, affecting both material tension (whether it's too tight or too loose) and line speed (whether the transmission speed is stable).

[0027] To properly control the tension (the degree of tension) and line speed (the speed of operation) during the unwinding process, it is essential to know the current coil diameter (also known as the "roll diameter"). Failure to calculate the roll diameter correctly can result in: unstable tension leading to coil breakage; speed mismatch leading to unstable equipment operation, reduced production efficiency, and increased quality issues.

[0028] There are two common methods for calculating coil diameter in the industry, but both have shortcomings: 1. Direct measurement: Use external sensors (such as displacement sensors, ultrasonic sensors, and laser ranging sensors) to directly read the roll diameter. However, these sensors are susceptible to external interference, resulting in large calculation errors. This increases equipment production and maintenance costs.

[0029] 2. Manual measurement method: Before loading, the initial diameter is measured manually with a steel ruler. However, this method has low measurement efficiency and cannot guarantee accuracy.

[0030] Based on this, an embodiment of the present application provides a roll diameter measuring device, through which the unwinding roll diameter is calculated in real time through the linkage relationship between the unwinding shaft 111 and the rocker arm 121 during the unwinding process to ensure the accuracy of tension control and line speed control.

[0031] See also Figure 1 The roll diameter measuring device includes a swing rod assembly 120 and a reel assembly 110; wherein the swing rod assembly 120 is connected to the reel assembly 110, and when the reel assembly 110 rotates, it can drive the swing rod assembly 120 to swing.

[0032] In some examples, such as Figure 2 As shown, several roller assemblies 130 are arranged between the rocker assembly 120 and the reel assembly 110. During the unwinding process, the unwinding shaft 111 unwinds the coil, and then the coil comes out of the unwinding shaft 111 and moves to the rocker assembly 120 through several roller assemblies 130. Finally, the coil comes out of the rocker assembly 120 and is released to the corresponding processing equipment or processing area through several roller assemblies 130.

[0033] For some examples, see Figure 2 In some examples, the reel assembly 110 includes an unwinding shaft 111 and a first motor 112 ; the first motor 112 is used to provide power to the unwinding shaft 111 to drive the unwinding shaft 111 to rotate.

[0034] Furthermore, the rocker assembly 120 includes a rocker 121 and a second motor 122 ; wherein the second motor 122 is used to provide power to the rocker 121 to drive the rocker 121 to move along a preset tension direction.

[0035] Optionally, the first motor 112 and the second motor 122 may be servo motors or stepper motors, which is not limited in this embodiment.

[0036] In this embodiment, the unwinding shaft 111 is the starting point for releasing the coil, which is usually driven by a motor or passively rotated to perform the actual unwinding operation; the speed of the unwinding shaft 111 needs to be precisely controlled according to the requirements of the downstream equipment to avoid the coil being too tight or loose.

[0037] The rocker arm 121 is a common tension control device used to monitor and adjust the tension of the roll material. It senses the position change of the roll material (such as up and down swing) and feeds back the signal to the corresponding control system (such as computer equipment, etc.), thereby adjusting the rotation speed of the unwinding shaft 111.

[0038] It is understandable that in order to ensure that the coil can be smoothly transferred from the unwinding shaft 111 to the subsequent processing equipment or processing area, the rocker assembly 120 is required to control the tension and position of the coil.

[0039] In one embodiment, when unwinding begins, the first motor 112 and the second motor 122 are started to provide power to the unwinding shaft 111 and the swing rod 121 respectively. The rotation of the unwinding shaft 111 drives the swing rod 121 to swing to monitor the tension and position of the unwinding.

[0040] In some examples, a first sensing component is provided in the reel assembly 110, and a second sensing component is provided in the rocker assembly 120. The first sensing component is used to record the real-time unwinding angle of the reel assembly 110, and the second sensing component is used to record the real-time moving distance of the rocker 121 when the rocker assembly 120 swings.

[0041] The first sensing component includes a first sensor, and the first sensor is used to collect the unwinding angle of the unwinding shaft 111 ; the second sensing component includes a second sensor, and the second sensor is used to collect the moving distance of the rocker 121 .

[0042] It should be noted that the first sensing component and the second sensing component correspond to the sensor components inherent in the scroll component 110 and the rocker component 120 , and are not additional external sensor components.

[0043] In one embodiment, the roll diameter measurement device further includes a computer device, wherein the computer device is in communication with the reel assembly 110 and the swing arm assembly 120. The computer device is configured to send instructions to the reel assembly 110 and the swing arm assembly 120 to control the movement of the reel assembly 110 and the swing arm assembly 120, receive signals or data transmitted by the reel assembly 110 and the swing arm assembly 120, and process the received signals and data.

[0044] During the unwinding process, the first sensing component in the reel assembly 110 transmits the real-time unwinding angle of the reel assembly 110 recorded in real time to the computer device, and the second sensing component in the rocker assembly 120 transmits the real-time movement distance of the rocker 121 collected in real time to the computer device. Then, after receiving the unwinding angle and movement distance, the computer device executes the coil diameter measurement method based on the internal computer program, calculates the actual coil diameter value of the coil according to the unwinding angle and movement distance received within a period of time, and outputs the coil diameter value.

[0045] Exemplarily, the computer device includes a processor and a memory, wherein the memory stores a computer program, and the processor runs the computer program, thereby enabling the computer device to execute the coil diameter measurement method.

[0046] Among them, the processor is used to send instructions to the reel assembly 110 and the rocker assembly 120 to trigger and control the movement of the reel assembly 110 and the rocker assembly 120, and receive signals or data transmitted by the reel assembly 110 and the rocker assembly 120 during the unwinding process to execute the coil diameter measurement method; the memory is used to store the signals and data received or generated by the processor.

[0047] Furthermore, the processor can be an integrated circuit chip with signal processing capabilities. The processor can be a general-purpose processor, including at least one of a central processing unit (CPU), a graphics processing unit (GPU), a network processor (NP), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. The general-purpose processor can be a microprocessor or any conventional processor, etc., and can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of this application.

[0048] The memory may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), and electrically erasable programmable read-only memory (EEPROM). The memory is used to store computer programs, and the processor can execute the computer programs accordingly after receiving an execution instruction.

[0049] It can be seen that this embodiment utilizes the sensor components inside the rocker assembly 120 and the reel assembly 110 to obtain the relevant changing parameters of the rocker 121 and the reel during the unwinding process, and then calculates the coil diameter based on the changing relationship between the reel rotation angle, the moving distance of the rocker 121 and the coil diameter during the unwinding process.

[0050] It can be understood that the present application utilizes the linkage between the internal movement changes of the reel assembly 110 and the rocker assembly 120 and the change in the roll diameter of the unwinding coil to reversely infer the actual roll diameter of the coil.

[0051] Based on the aforementioned roll diameter measuring device, an embodiment of the present application also provides a roll diameter measuring method, which is applied to the roll diameter measuring device of the aforementioned embodiment; in this embodiment, the change in the roll rotation angle and the movement displacement of the rocker arm 121 within a time period during the unwinding process is mapped and calculated to obtain the change in the roll diameter of the roll during the unwinding period, and then the actual length of the roll diameter of the roll is inferred.

[0052] Obviously, without using external sensors, this embodiment can avoid the impact of product costs, maintenance costs, installation location requirements and measurement environment requirements that exist when using external sensors, and at the same time, no manual measurement is required; therefore, without the need for additional installation of sensors or manual measurement, the actual roll diameter of the coil can be quickly and accurately calculated using only the internal sensor component.

[0053] That is, the present application provides a method for calculating the coil diameter by rotating the reel to drive the pendulum 121 to swing, and using the angle and displacement, which can be applied to automated equipment or application scenarios such as lithium battery production that require precise control of coil tension and speed.

[0054] For reference, such as Figure 3 As shown, the coil diameter measurement method includes the following steps: S310 , controlling the reel assembly 110 to rotate to pull the swing arm assembly 120 to swing, and obtaining the relative movement distance of the swing arm 121 when the swing arm assembly 120 swings.

[0055] S320 , when the relative moving distance reaches the preset moving distance, the scroll assembly 110 is controlled to stop rotating, and the relative rotation angle of the scroll assembly 110 during this rotation is obtained.

[0056] S330: Calculate the coil diameter based on the relative rotation angle and the preset movement distance.

[0057] In this embodiment, the computer device in the roll diameter measuring device sends control instructions to the reel assembly 110 and the rocker assembly 120. The control instructions are used to trigger the start of the motors in the reel assembly 110 and the rocker assembly 120, thereby controlling the movement of the unwinding shaft 111 and the rocker 121 to perform the unwinding operation.

[0058] It can be understood that during the unwinding process, the sensor components in the reel assembly 110 and the rocker assembly 120 respectively obtain the rotation angle of the unwinding shaft 111 and the moving distance of the rocker 121.

[0059] After receiving the moving distance, the computer device calculates the relative moving distance of the rocker arm 121 during this unwinding process. If it is determined that the relative moving distance is equal to the preset moving distance, a stop command is sent to the reel assembly 110 and the rocker arm assembly 120 to control the reel assembly 110 and the rocker arm assembly 120 to stop moving, and obtains the relative rotation angle of the reel assembly 110 during this unwinding process. A mathematical model is then established based on the relative rotation angle and the preset moving distance to calculate the roll diameter of the coil.

[0060] The relative movement distance is equal to the current movement distance minus the movement distance before unwinding; and the relative rotation angle is equal to the current rotation angle minus the rotation angle before unwinding.

[0061] For example, first obtain the initial unwinding angle of the reel assembly 110 before this rotation and the current unwinding angle corresponding to the moment of stopping rotation; subtract the initial unwinding angle from the current unwinding angle to obtain the relative rotation angle of the reel assembly 110 during this rotation.

[0062] Similarly, first obtain the initial moving distance of the rocker assembly 120 before this swing, and the current moving distance when the rocker assembly 120 stops swinging without being pulled by the rotation of the reel assembly 110; calculate the relative moving distance based on the current moving distance and the initial moving distance.

[0063] In some examples, the preset moving distance is determined based on the thickness and material of the coil. That is, in this embodiment, different preset moving distances can be set in advance according to the thickness or material of the coil; optionally, the thicker the coil, the greater the preset moving distance. In this embodiment, the value of the preset moving distance is set accordingly according to actual needs and is not limited to this. In other words, this embodiment can be applied to the calculation of the coil diameter of coils of various materials and different thicknesses. In addition, this embodiment can also flexibly adapt to coils of different materials and thicknesses, as well as different unwinding speeds and tension requirements, by adjusting the preset value of the rocker 121 and the control parameters of the motor, thereby expanding the application scenarios.

[0064] Furthermore, in the process of establishing a mathematical model based on the relative rotation angle and the preset moving distance to calculate the coil diameter of the coil, the unwinding circumference is first calculated based on the relative rotation angle and the preset moving distance; then, the coil diameter is calculated based on the unwinding circumference.

[0065] The quotient of the relative rotation angle and the circumference is first calculated, that is, the circumference is divided by the relative rotation angle to obtain the target angle value; wherein the circumference is 360 degrees.

[0066] Next, the product of the target angle value and the preset moving distance is calculated to obtain the unwinding circumference; and then the unwinding circumference is divided by pi to obtain the coil diameter.

[0067] For example, if the relative rotation angle is recorded as A, the target angle value is recorded as B, the preset movement distance is recorded as L, the unwinding circumference is recorded as C, and the winding diameter is recorded as D, then: B=360 / A, C=B*L, D=C / π=360 / A*L / π.

[0068] It can be understood that when the unwinding shaft 111 begins to rotate, releasing the coil, and the relative displacement of the swing arm 121 reaches a preset value, the unwinding shaft 111 and the swing arm 121 are controlled to stop rotating. This allows the angular change from the start to the stop of the unwinding shaft 111 to be calculated (A = end angle - start angle), and the unwinding circumference is then calculated based on this angular change (C = 360 / A * preset travel distance). The circumference of the coil is then calculated based on the travel distance of the swing arm 121 and the angle of rotation of the unwinding shaft 111 (unwinding coil diameter = unwinding coil circumference / π). This is done by using the circumference formula of a circle (C = Dπ) to infer the coil diameter.

[0069] In short, assuming that the movement of the swing arm 121 is due to the rotation of the unwinding shaft 111, the length of one revolution (i.e., the circumference) can be inferred from this distance. Based on the circumference of the simulated coil, the coil diameter can be inferred. In other words, based on the relationship between the rotation angle of the unwinding shaft 111, the movement distance of the swing arm 121, and the change in the length of the unwound coil, the circumference of one revolution of the coil can be calculated, and thus the coil diameter.

[0070] In some examples, if the specific structure or control method of the rocker arm 121 and the unwinding shaft 111 changes, the coil diameter calculation process can still be based on the same principle, that is, calculating the coil diameter based on the displacement of the rocker arm 121 and the unwinding angle. As can be seen, the coil diameter calculation method of this embodiment is relatively stable and applicable to various application scenarios. The entire process does not rely on external sensors and is therefore not restricted by issues such as sensor installation location and web obstruction. This makes the coil diameter calculation method of this embodiment highly adaptable and stable under various working conditions and environments.

[0071] Furthermore, this embodiment uses a motor to control the unwinding rocker 121 and unwinding shaft 111, enabling fast and precise response. When the relative displacement of the rocker 121 reaches a preset value, the unwinding shaft 111 quickly stops unwinding, ensuring accurate calculations. Furthermore, the precise control provided by the motor allows for accurate measurement of the unwinding angle and the displacement of the rocker 121, thereby improving the accuracy of the roll diameter calculation.

[0072] This embodiment does not need to rely on external sensors or manual measurement methods, but instead dynamically calculates the roll diameter through the structure of the device itself. Compared with the direct measurement method that relies on external sensors, this embodiment reduces the purchase, installation and maintenance costs of the sensors, and is therefore relatively more convenient in terms of maintenance and servicing. The maintenance and servicing of the motor are also relatively simple, reducing maintenance costs and time. During the unwinding process, this embodiment can use a motor to control the rocker arm 121 and the unwinding shaft 111, so that it can respond quickly and accurately stop unwinding, and also reduce the need for high-precision sensors. By adjusting the preset value of the rocker arm 121 and the motor parameters, it can adapt to coils of different materials and thicknesses, expanding the scope of application scenarios for coil diameter calculation.

[0073] In summary, this embodiment realizes the calculation of the coil diameter by accurately measuring the unwinding angle and the displacement of the rocker arm 121. This method not only improves the accuracy of the coil diameter calculation, but also the entire calculation process does not rely on external sensors and is not affected by problems such as the sensor installation position and strip obstruction, thereby reducing the purchase, installation and maintenance costs of external sensors. At the same time, it also does not require a complex sensor system, and the maintenance of the motor is relatively simple, reducing maintenance costs.
